Input data standardisation
Posted: Mon Nov 21, 2011 2:11 pm
Before we input the data should we standardise it or mean center it especially when we have some moderating variables to check

It is not necessary,
The first step in the algorithm PLS is the standardization, and when you will run the moderation analysis, the SmartPLS has options to mean centered, standardized etc. See release.php

Would you please let me know how to do data standardization , as a first step in PLS? Please note, I dont have moderating variables

You do not need to do this, the algorithm PLS already do it.
Z = (Xi - Xbar)/s.d.
